Abstract(s)
Atualmente, a grande maioria dos Sistemas de Tecnologias de Informação (STI) existentes
nas instituições de ensino superior estão implementados segundo paradigmas tradicionais. O
uso dessas abordagens dificulta a implementação de sistemas de alta capacidade que garantam
escalabilidade e maior disponibilidade. Tendo por exemplos, a disponibilidade de plataformas
de apoio ao ensino, e.g: Moodle ou, à flexibilidade de acesso remoto a laboratórios
informáticos, os sistemas atualmente implementados precisam de dar resposta às necessidades
atuais de forma versátil e eficiente.
Os avanços nos últimos anos no domínio de Cloud Computing e Infrastructure as Code,
possibilitam uma fácil adoção ao paradigma das tecnologias de Cloud Computing. Estes
avanços apresentam diversos benefícios para as instituições de ensino superior, através da
simplificação da configuração dos sistemas, automatização de processos, redução de custos de
infraestrutura em conjunto com a otimização da utilização dos recursos preexistentes assim
como uma fácil adaptação aos diferentes requisitos que surgem da rápida e constante evolução
dos STI.
Associados aos benefícios para as instituições de ensino superior, existe também um benefício
transversal de melhoria do processo de ensino, principalmente no ensino de disciplinas de
Engenharia Informática. A adoção deste paradigma oferece a este nicho, ferramentas e
plataformas que contribuem para a melhoria da eficiência do ensino mediante a
disponibilidade de laboratório informáticos virtuais, acesso remoto e de aprovisionamento e
configuração de infraestrutura on-demand.
Contudo, a implementação e configuração destes processos é um problema complexo e que
produz elevada entropia na configuração de vários sistemas heterogéneos. Neste âmbito, o
presente trabalho visa propor e implementar uma arquitetura de Private Cloud recorrendo à
plataforma Openstack no contexto do ensino superior e ao uso de ferramentas de
aprovisionamento e configuração como o Ansible, oferecendo uma implementação
estandardizada e automatizada. De forma a ilustrar a sua aplicabilidade são também
apresentados e discutidos casos de uso que veiculam os processos com as plataformas
propostas para serem utilizadas pela comunidade da instituição de ensino superior.
ABSTRACT: Currently, most of the Information Technology Systems (ITS) existing in higher education institutions are implemented according to traditional paradigms. The use of these approaches makes it difficult to implement high-capacity systems that ensure scalability and greater availability. With examples of the availability of education support platforms, e.g., Moodle or the flexibility of remote access to computer labs, the systems currently implemented need to meet current needs in a versatile and efficient way. The advances in recent years in the field of Cloud Computing and Infrastructure as Code, allow an easy adoption to the paradigm of Cloud Computing technologies. These advances present several benefits for higher education institutions, through the simplification of systems configuration, process automation, reduction of infrastructure costs in conjunction with the optimization of the use of pre-existing resources as well as an easy adaptation to the different requirements that arise from the rapid and constant evolution of ITS. Alongside the advantages introduced for higher education institutions, there is also a crosscutting benefit of improving the teaching process, especially in the teaching of Computer Engineering disciplines. The adoption of this paradigm offers this niche tools and platforms that contribute to the improvement of the efficiency of teaching through the availability of virtual computer labs, remote access and provisioning and configuration of on-demand infrastructure. However, the implementation and configuration of these processes is a complex problem and produces high entropy in the configuration of various heterogenous systems. In this context, the present work aims to propose and implement a Private Cloud architecture using the Openstack platform in the context of higher education and the use of provisioning and configuration tools such as Ansible, offering a standardized and automated implementation. To illustrate its applicability, use cases that convey the processes with the proposed platforms to be used by the community of the higher education institution are also presented and discussed.
